Title: Proportional flow rate valve
Inventor: DORIYUU PII RAMAAKA
IPC: F16K31/06
Filed: 1990-09-06
Abstract: PURPOSE: To hold valve opening in correspondence with the fluctuation of inlet fluid pressure by constituting a proportional flow valve in such structure that the moving distance of a valve member from a valve seat against an elastic means is proportional to the current value applied to a solenoid actuator. CONSTITUTION: When a current is applied to a coil 10 of a solenoid actuator 9, a contact 28 is moved downward against a spring 32, and a pilot valve member 61 is first opened through a rigid tube 65 to lead primary side gas pressure to the upper part of a diaphragm 77 from a side hole 82 of the rigid tube 65 so as to be balanced with closing force based on the primary side gas pressure of a main valve member 51. In this state, the main valve member 51 descends while compressing a spring 54 in proportion to the current value to the coil 10 so as to open an opening of specified shape provided at a guide 57 coming in sliding contact with a valve seat.  Valve closing force by inlet fluid pressure is thus offset to obtain the position of the valve member, that is, a flow rate, proportional to the current value to the actuator, and the valve can be automatically closed at the time of the failure of the actuator.
